* Installation Changes in Emacs 23.1
** The default X toolkit is now Gtk+, rather than Lucid.
+The configure option `--with-gtk' has been removed. Gtk is now the
+default toolkit, but you can use --with-x-toolkit=gtk if necessary.
-** Fonts are handled by new code capable of dealing with multiple font
-backends. This requires the freetype and fontconfig libraries, and
-supports local fonts (fonts installed on the machine where Emacs is
-running). Additionally, the Xft library can be used for antialiasing
-support, the otf library for complex text layout by OpenType fonts,
-and the m17n library for text shaping. Emacs now accepts font names
-supplied in the fontconfig format (e.g. "monospace-12:bold") and GTK
-format (e.g. "Monospace Bold 12").

* Changes in Emacs 23.1
-** `underline-minimum-offset' keeps the underline away from the baseline.
+** Improved X Window System support
-** Info displays breadcrumbs in the header of the page.
-See Info-breadcrumbs-depth to control it.
+*** Emacs now supports using both X displays and ttys in one session.
+With an Emacs server active (M-x server-start), `emacsclient -t'
+creates a tty frame connected to the running emacs server. You can
+use any number of different ttys. `emacsclient -c' creates a new X11
+frame on the current $DISPLAY (or a tty frame if $DISPLAY is not set).
-** Emacs now supports serial port access on GNU/Linux, Unix, and
-Windows. `serial-term' starts an interactive terminal,
-`make-serial-process' and `serial-process-configure' provide a Lisp
-interface. The serial port can be configured at runtime with the
-mode-line mouse menu.
+You can test for the presence of this feature in your Lisp code by
+testing for the `multi-tty' feature.
-** Apropos
-*** `apropos-library' describes the elements defined in a given library.
-*** Set `apropos-compact-layout' is you want a more compact (but wider) layout.
+**** Emacsclient can now open new terminal frames.
+Now, the default behavior is to open a new Emacs frame by default.
+Use the -c option to get the old behavior of opening files in the
+currently selected Emacs frame.
+
+*** The new command close-display-connection closes a connection to a
+remote display.
+
+*** Emacs now supports the XEmbed specification.
+You can embed Emacs in another application on X11. The new command line
+option --parent-id is used to pass the parent window id to Emacs. See
+http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html
+for details about XEmbed.
-** scroll-preserve-screen-position also preserves the column position.
-** Completion.
-*** `completion-styles' can be customized to choose your favorite completion.
-*** The default completion styles include a form of partial-completion.
-*** The new command `minibuffer-force-complete chooses one of the possible
-completions, rather than stopping at the common prefix.
-*** `completion-auto-help' can be set to `lazy' to list the completions only
-if you repeat the completion. This was already supported in
-`partial-completion-mode'.
+*** Emacs can now set the frame opacity.
+The opacity of a frame can be controlled by setting the `alpha' frame
+parameter. This only takes effect on a compositing window manager for
+the X Window System, such as Compiz, Beryl and Compiz Fusion.
-** Emacs now supports using both X displays and ttys in one session.
-Start the server (M-x server-start). Then `emacsclient -t' creates a
-tty frame connected to the running emacs server. You can also use any
-number of different ttys. `emacsclient -c' creates a new X11 frame on
-the current $DISPLAY or a tty frame if $DISPLAY is not set.
+The alpha parameter should be an integer between 0 (transparent) and
+100 (opaque), or a float number between 0.0 and 1.0. It can also be a
+cons cell (ACTIVE . INACTIVE), where ACTIVE is the opacity of an
+active frame and INACTIVE is the opactity of non-active frames.
-You can test for the presence of this feature in your Lisp code by
-testing for the `multi-tty' feature.
+The variable `frame-alpha-lower-limit' defines a lower bound for the
+opacity; the default is 20.
-** The Emacs character set is now a superset of Unicode.
+** Internationalization changes
+
+*** The Emacs character set is now a superset of Unicode.
(It has about four times the code space, which should be plenty).
The internal encoding used for buffers and strings is now
-Unicode-based and called `utf-8-emacs'. utf-8-emacs is backwards
-compatible with the UTF-8 encoding of Unicode. The `emacs-mule'
-coding system can still read and write data in the old internal encoding.
-
-Since the internal encoding is also used by default for byte-compiled
-files -- i.e. the normal coding system for byte-compiled Lisp files is
-now utf-8-Emacs -- Lisp containing non-ASCII characters which is
-compiled by Emacs 23 can't be read by earlier versions of Emacs. Files
-compiled by Emacs 20, 21, or 22 are loaded correctly as emacs-mule
-(whether or not they contain multibyte characters), which makes loading
-them somewhat slower than Emacs 23-compiled files. Thus it may be worth
-recompiling existing .elc files which don't need to be shared with older
-Emacsen.
+Unicode-based and called `utf-8-emacs'. This encoding is backwards
+compatible with Unicode's UTF-8 encoding. The internal encoding
+previously used by Emacs, `emacs-mule', is still available.
+
+During byte-compilation, Emacs 23 uses `utf-8-emacs' to write files.
+As a result, byte-compiled files containing non-ASCII characters can't
+be read by earlier versions of Emacs. Files compiled by Emacs 20, 21,
+or 22 are loaded correctly as emacs-mule (whether or not they contain
+multibyte characters). This takes somewhat more time, so it may be
+worth recompiling existing .elc files which don't need to be shared
+with older Emacsen.

+*** There is a new charset implementation with many new charsets.
See M-x list-character-sets. New charsets can be defined conveniently
as tables of unicodes.
-The dimension of a charset is now 1, 2, 3, or 4, and the size of each
-dimension is no longer limited to 94 or 96.

-** There are new Chinese-GBK, Chinese-GB18030, Khmer, Bengali,
-Punjabi, Gujarati, Oriya, Telugu, Sinhala, and TaiViet language
-environments.
-
-** Emacs now supports the XEmbed specification.
-You can embed Emacs in another application on X11. The new command line option
---parent-id is used to pass the parent window id to Emacs. See
-http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html
-for details about XEmbed.
-
-** Controlling the frame opacity
-The opacity of a frame can now be controlled by setting
-the `alpha' frame parameter, on a compositing window manager
-(e.g. Compiz, Beryl and Compiz Fusion) for the X Window System.
-
-The alpha parameter should be an integer between 0 (transparent) and
-100 (opaque) or a float number between 0.0 and 1.0. Optionally, the
-opacity can be set by a cons cell; the first item controls the
-opacity of an active frame, and the second item controls that of
-non-active frames.
-
- (set-frame-parameter nil 'alpha 80)
- (set-frame-parameter nil 'alpha 0.8)
- (set-frame-parameter nil 'alpha '(100 70)) ; (<active> [<inactive>])
- (set-frame-parameter nil 'alpha nil)
-
-Note that the threshold opacity of a frame is defined by the variable
-`frame-alpha-lower-limit' (default 20), so that the user may not lose
-control of the frame.
-
-** Emacs comes with a new set of default icons.
-Various resolutions are available as etc/images/icons/hicolor/*/apps/emacs.png.
-The Emacs 22 icon is available as `emacs22.png' in the same location.
+*** There are new language environments for Chinese-GBK,
+Chinese-GB18030, Khmer, Bengali, Punjabi, Gujarati, Oriya, Telugu,
+Sinhala, and TaiViet.
-** Built-in functions (subr) can now have an interactive specification
-that is not a prompt string. If the `intspec' parameter of a `DEFUN'
-starts with a `(', the string is evaluated as a Lisp form.
+*** The minor modes unify-8859-on-encoding-mode and
+unify-8859-on-decoding-mode are obsolete.
-** set-file-modes is now interactive and can take the mode value in
-symbolic notation thanks to auxiliary functions.
-
-** Changes affecting display-buffer
-*** New value nil for split-height-threshold inhibits vertical splitting
-unless there's no other window.
-*** New option split-width-threshold controls horizontal splitting.
-*** A window can be split horizontally even when it's not full-width.
-*** New option split-window-preferred-function can be set to a function
-to override the default splitting mechanism of display-buffer.
+** Emacs now supports serial port access on GNU/Linux, Unix, and
+Windows. `serial-term' starts an interactive terminal,
+`make-serial-process' and `serial-process-configure' provide a Lisp
+interface. The serial port can be configured at runtime with the
+mode-line mouse menu.
** Menu Bar changes
-*** The Options menu contains a new entry to turn on Longlines mode.
-
*** In the Options menu, the "Set Default Font" item applies the
selected font to the `default' face on all frames, not just the
-current frame. This font setting will be saved if the "Save Options"
-item is used. Furthermore, if Emacs is compiled with both GTK and
+current frame. Furthermore, if Emacs is compiled with both GTK and
Fontconfig support, the "Set Default Font" item uses the GTK font
selection dialog instead of an Emacs pop-up menu.
-** Emacsclient has been extended to support opening a new terminal
-frame. Its behavior has been changed to open a new Emacs frame by
-default. Use the -c option to get the old behavior of opening files in
-the currently selected Emacs frame.
-
-** The refcards are now shipped as PDF files.
-
-** Emacs now supports the SVG image format through librsvg2.
-
-** If you set find-file-confirm-nonexistent-file to t, then C-x C-f
-requires confirmation before opening a non-existent file.
-
-** If the gpm mouse server is running and t-mouse-mode enabled, Emacs uses a
-Unix socket in a GNU/Linux console to talk to server, rather than faking events
-using the client program mev. This C level approach provides mouse
-highlighting, and help echoing in the minibuffer.
-
-** Recentering changes
-
-*** The new variable next-error-recenter specifies how next-error should
-recenter the visited source file. Its value can be a number (for example,
-0 for top line, -1 for bottom line), or nil for no recentering.
-
-*** New command recenter-top-bottom moves the current line to window
-center, top and bottom on successive invokations.
-
-*** C-l is bound to the new command recenter-top-bottom, rather than recenter.
-
-** The mode-line displays a `@' if the default-directory for the current buffer
-is on a remote machine, or a hyphen otherwise.
-
-** The mode-line displays a mode menu when mouse-1 is clicked on a minor mode,
-in the same way as it already did for major modes.
-
-** The new command balance-windows-area balances windows both vertically
-and horizontally.
-
-** The new command close-display-connection can be used to close a connection
-to a remote display, e.g. because the display is about to become unreachable.
-
-** The command shell prompts for the default directory, when it is
-called with a prefix, and the default directory is a remote file name.
-This is because some file name handlers (like ange-ftp) are not able to
-run processes remotely.
-
-** The new command `display-time-world' starts an updating time display
-using several time zones, in a buffer.
-
-** Directory-local variables are now found in .dir-settings.el. See
-also `set-directory-project' and `define-project-bindings'.
+*** The font setting chosen by "Set Default Font" is saved if the
+"Save Options" item is used.
-** The new function `format-seconds' converts a number of seconds into a
-readable string of days, hours, etc.
+*** The Options menu contains a new entry to turn on Longlines mode.
-** The new variables `before-init-time' and `after-init-time' record the
-value of `current-time' before and after Emacs loads the init files.
+** Mode-line changes
-** The new function `emacs-uptime' returns the uptime of an Emacs instance.
+*** The mode-line displays a `@', instead of `-', if the
+default-directory for the current buffer is on a remote machine.
-** The new function `emacs-init-time' returns the duration of the
-Emacs initialization.
+*** The mode-line displays a mode menu when mouse-1 is clicked on a
+minor mode, in the same way as it already did for major modes.
-** The minor modes unify-8859-on-encoding-mode, unify-8859-on-decoding-mode
-are obsolete.
+*** The `mode-line-emphasis' face is used to highlight certain
+mode-line information (e.g. waiting for a VC command to finish).
-** The new commands `pp-macroexpand-expression' and `pp-macroexpand-last-sexp'
-pretty-print macro expansions.
+** Directory-local variables can now be defined.
+By default, Emacs looks in .dir-settings.el for directory-local
+variables. For more information, see `set-directory-project' and
+`define-project-bindings'.
